Abstract: A method by which a terminal transmits feedback information comprises the steps of: determining, in predetermined resource units for receiving the broadcast information in a broadcast resource region, whether broadcast information collides; selecting a first shared resource in a shared resource region corresponding to a first broadcast resource in which the conflict occurs in the broadcast resource region, on the basis of a pre-defined mapping rule of the broadcast resource region and the shared resource region; and transmitting, in the selected first shared resource, feedback information including information on the occurrence of the collision, wherein the broadcast resource region is a resource region, which is defined so as to transmit or receive the broadcast information, and the shared resource region can be determined as a resource region shared between a plurality of terminals. The UE is capable of communicating with at least one of another UE, a UE related to an autonomous driving vehicle, a base station or a network.

Abstract: Disclosed are a method for receiving a downlink channel by a terminal in a wireless communication system and a device therefor. More particularly, a method for receiving a downlink channel by a terminal in a wireless communication system comprises the steps of: receiving, from a base station, configuration information relating to a plurality of transmission beams of the base station, wherein the configuration information comprises configuration items with respect to one or more beam sets comprising the plurality of transmission beams; receiving information indicating any one beam set among the one or more beam sets from the base station; and receiving a downlink control channel from the base station by means of the indicated beam set, wherein, if the information indicating any one beam set is not received from the base station, the downlink control channel can be received by means of a pre-configured beam set among the beam sets.

Abstract: A disclosure of the present specification provides a method for determining transmission power of an uplink channel. The method may comprise the steps of: selecting the maximum transmission power from among transmission power of multiple uplink channels transmitted to a specific serving cell in a first subframe; and when a first uplink channel has transmission power lower than the maximum transmission power and the transmission power is smaller than the difference between the maximum transmission power and a first threshold, determining boosting of the transmission power of the first uplink channel. Here, the multiple uplink channels may comprise one or more of an uplink data channel, an uplink control channel, and an uplink reference signal.
